Question

我想知道是否有人可以帮助我...我有一个返回xml结果的存储过程。我需要将此结果保存为以下格式的文本文件：

CLEAR

CHIAVE REG

VEND REP = 1，qty = 1，PRICE = 130，DES ='coffee'

CHIU TEND = 1

数量，价格和描述来自xml结果。这可能吗？在此先感谢... :)

您可以构建varchar字符串并将其保存到文本文件的末尾。这里的限制是最大varchar值（8000）。

我用过这个sproc来做它;

alter PROCEDURE spWriteStringToFile
 (
@String Varchar(max), --8000 in SQL Server 2000
@Path VARCHAR(255),
@Filename VARCHAR(100)

--
)
AS
DECLARE  @objFileSystem int
        ,@objTextStream int,
        @objErrorObject int,
        @strErrorMessage Varchar(1000),
        @Command varchar(1000),
        @hr int,
        @fileAndPath varchar(80)

set nocount on

select @strErrorMessage='opening the File System Object'
EXECUTE @hr = sp_OACreate  'Scripting.FileSystemObject' , @objFileSystem OUT

Select @FileAndPath=@path+'\'+@filename
if @HR=0 Select @objErrorObject=@objFileSystem , @strErrorMessage='Creating file "'+@FileAndPath+'"'
if @HR=0 execute @hr = sp_OAMethod   @objFileSystem   , 'CreateTextFile'
    , @objTextStream OUT, @FileAndPath,2,True

if @HR=0 Select @objErrorObject=@objTextStream, 
    @strErrorMessage='writing to the file "'+@FileAndPath+'"'
if @HR=0 execute @hr = sp_OAMethod  @objTextStream, 'Write', Null, @String

if @HR=0 Select @objErrorObject=@objTextStream, @strErrorMessage='closing the file "'+@FileAndPath+'"'
if @HR=0 execute @hr = sp_OAMethod  @objTextStream, 'Close'

if @hr<>0
    begin
    Declare 
        @Source varchar(255),
        @Description Varchar(255),
        @Helpfile Varchar(255),
        @HelpID int

    EXECUTE sp_OAGetErrorInfo  @objErrorObject, 
        @source output,@Description output,@Helpfile output,@HelpID output
    Select @strErrorMessage='Error whilst '
            +coalesce(@strErrorMessage,'doing something')
            +', '+coalesce(@Description,'')
    raiserror (@strErrorMessage,16,1)
    end
EXECUTE  sp_OADestroy @objTextStream
EXECUTE sp_OADestroy @objTextStream
